Description

GE DS3800HSQD1J1G

Technical Specifications

  • Manufacturer: General Electric (GE)
  • Product Series: Speedtronic / Industrial Drives
  • Board Type: Servo Valve Control PCB
  • Output: High-precision current drive for servo valves

Functional Features

  • Precise Positioning: Delivers accurate current signals to position hydraulic servo valves.
  • Feedback Processing: Continuously monitors LVDT (Linear Variable Differential Transformer) feedback to ensure correct valve stroke.
  • Fail-Safe Operation: Includes hardware and software protections to drive valves to a safe state in the event of a fault.

Application Scenarios
Gas and steam turbine fuel control systems, hydraulic actuator positioning, and high-precision industrial motion control.

Performance Parameters

  • Response Time: Millisecond-level dynamic response to control commands.
  • Positioning Accuracy: High-resolution output for smooth and stable valve control.

Material Composition
Built with precision analog components, low-drift resistors, and high-reliability current drivers on a multi-layer PCB.

Structural Characteristics
Standard control board form factor with dedicated connectors for servo valve wiring and LVDT feedback signals.

Working Principle
Receives a position command from the main controller, compares it with the actual LVDT feedback, and adjusts the output current to the servo valve coil to minimize the error.

Installation Requirements
Install in the designated slot within the control rack. Ensure all servo and feedback cables are properly shielded and routed away from high-voltage power lines.

Usage Precautions
Verify the servo valve and LVDT wiring polarity before applying power. Do not disconnect the servo valve while the system is energized.
